Fingerprint Pro for Android

Inspect device identity with Fingerprint Pro

Fingerprint Pro is an Android utility that demonstrates the capabilities of the Fingerprint Identification SDK. The SDK creates a unique identifier tied to each device; that identifier persists across reboots and even after a factory reset. The app is intended as an experimental environment for developers and curious users who want to see how device-level identity information can be used.

Key capabilities you can try

• Distinguishes whether the device is running as an emulator or on real hardware
• Reports if the device has been rooted or otherwise modified
• Displays when the last factory reset occurred
• Generates and exposes a persistent device identifier that remains stable across restarts and resets

How it’s useful

Fingerprint Pro provides a hands-on way to understand how persistent device identifiers and system status signals can help applications:

• Improve user experience by recognizing returning devices
• Detect and reduce fraud or abuse by identifying suspicious device changes
• Aid debugging and device intelligence tasks during development and testing

Extra note and an alternative

If you’re browsing recommended apps, an unrelated suggestion that sometimes appears alongside utilities is ND Filter Calc (DSLR) — a free tool for photographers. It’s a different category (camera exposure/ND filter calculations) rather than a device-identification utility, but you may see it listed as a top alternative in some stores.
